Title: Materials Data on LiMnPO4 by Materials Project

Abstract

LiMnPO4 is Chalcostibite-derived structured and crystallizes in the trigonal P31c space group. The structure is three-dimensional. Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with two equivalent LiO4 tetrahedra, corners with four PO4 tetrahedra, and corners with three equivalent MnO5 trigonal bipyramids. There are a spread of Li–O bond distances ranging from 1.97–2.02 Å. Mn2+ is bonded to five O2- atoms to form distorted MnO5 trigonal bipyramids that share corners with three equivalent LiO4 tetrahedra, corners with five PO4 tetrahedra, and edges with two equivalent MnO5 trigonal bipyramids. There are a spread of Mn–O bond distances ranging from 2.09–2.35 Å. There are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent LiO4 tetrahedra and corners with six equivalent MnO5 trigonal bipyramids. There is three shorter (1.55 Å) and one longer (1.59 Å) P–O bond length. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with six equivalent LiO4 tetrahedra and corners with three equivalent MnO5 trigonal bipyramids. There is one shorter (1.55 Å) and three longer (1.56more » Å) P–O bond length. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent LiO4 tetrahedra and corners with six equivalent MnO5 trigonal bipyramids. There is three shorter (1.55 Å) and one longer (1.58 Å) P–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Li1+, one Mn2+, and one P5+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Mn2+, and one P5+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Mn2+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to three equivalent Mn2+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Mn2+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a tetrahedral geometry to three equivalent Li1+ and one P5+ atom.« less
